HEEL-TRIMMING MACHINE.

PECIFIQATIN forming part of Letters Patent No. 328,854, dated October 20, 1885, Application filed June 18, 1885. Serial No. 169,026. (No model.)

To all whom it may concern:

Be it known that we, JAMES L. LORD and NnLsoN Ross, of Lynn, in the county of Essex and State of Massachusetts, have invent ed certain new and useful Improvements in Heel-Trimming Machines, of which the f0llowing is a specification.

This invention relates to heel trimming and burnishing machines in which a rotary tool is employed, driven by suitable power; and it consists, first, in the combination, with such tool, of a positively-rotated roll arranged to support the heel while it is being presented to the tool, its positive rotation being in such direction that it feeds or presses the heel against the tool, and thus materially aids the operator.

The invention also consists in a non rotating bearing plate or support for the top lift, combined with a rotary trimming cutter, which is made in two sections, one of which is movable toward and from the other, and

with a suitable guide, which prevents the plate from rotating, all of ceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a heel-trimming machine having our improvements, the cutter being shown in section. Fig. 2 represents a section on line as :r, Fig. 1. Fig. 3 represents an end view.

The same letters of reference indicate the same parts in all the figures.

In the drawings, t represents a rotary tool, here shown as a' trimming-cutter adapted to form the molded face of a heel.

7) represents the arbor on which the cutter is mounted, said arbor being journaled in a frame, a, rotated by a belt or other suitable means in the direction indicated by the arrow in Fig. 3.

d represents an arbor journaled in which we will now probearings a pulley, e, to receive a drivingbelt. To said arbor is affixed a roll, f, which is arranged somewhat below and in advance of the cutter 1, so that it is capable of supporting a heel presented to the cutter. The arbor d and its roll are rotated in a direction opposite to that in which the cutter is rotated, as indicated in Fig. 3, so that the roll not only supports the heel, but feeds or presses it against the cutter. The

workman is therefore required to exert much less effort in presenting the heel than he would be if the positively-rotated roll were not employed. When used with a trimming-cutter, the roll f preferably has a corrugated periphery to enable it to take a better hold on the work. Should the roll be used with a rotary burnisher, it would be best to provide it with a yielding rubber covering, to give it friction on the heel without indenting it.

We have shown the trimming-tool made in two sections, a and a, as shown in the application of J. L. Lord, one of the present a plicants, filed May6, 1885, N 0. 164,597. The section a is rigidly attached to the arbor I), while the section a is adapted to move on said arbor toward and from the section a, and is pressed toward the section a by a spring, 9. The section a has a lip or guard, 2, projecting between the heel-seat and upper, while the section a has a beveled guard or rest, 3, for the face of the top lift. The section a has a screw, 0, entering a longitudinal groove in the arbor b, and causing the section a to rotate with the arbor. The object of this sectional construction is to enable the cutter to accommodate itself in width to the different parts of the heel, the rear part usually being wider than the sides in heels of ladies boots. As the top lift is formed by a die before its application to the heel, and therefore needs no trimming, a plain surface or rest having no cutting-teeth is provided for it in trimming cutters, said surface being generally flush with the molded cutting-surface. We construct this rest in the form of a plate, z, having an orifice receiving a boss, j, on the section a. The plate z is not attached to said section, and is provided with an arm or offset, 6, which has an orifice through which the arbor 01 passes. The periphery of the main portion of the plate *5 is flush with the molded surface of the cutter, and constitutes a nonrotating rest for the edge of the top lift, the plate a being prevented from rotating by the boss j and arbor d.

The advantage of a non-rotating rest for the edge of the top lift is, that the top lift is not burned by the friction attending the use of a rest affixed to the tool. When the section a slides on the arbor b, the plate i, moving freely on the arbor d, slides with said section,

We are aware that a loose roll has been used as a support for the heel in a trimming machine, but are not aware that a positivelyrotated one has ever been used.

The advantages of a rotated over a loose roll are obvious, and need not be repeated.

We are also aware that a non-rotating rest for the top-lift .edge has been used in a trimming-machine, and do not, therefore, claim the same, excepting as constructed and combined by us.

1. The combination, with a positively -.r.otated tool formed to act on a boot or shoe heel, of a heel supporting and feeding roll, and means, substantially as described, for positively rotating said feeding-roll in a direction opposite to the direction of rotation of the tool, as set forth.
